Application illed October 9, 1922. Serial No. 593,268.

The invention relates to wringers and refers particularly to wringers ofthat type in which the rolls are separated by a spring. One of theobjects of the invention is to provide a simple compact mechanlsm in thewringer for moving the rolls int-o contact with'each other and forseparating thesame.I Further objects of the invention reslde in thenovel features of constructionand combinations and arrangements of partsas more fully hereinafter set frth.

' In the drawings: Y

Figure 1 is a side elevation partly in section of a Wringer embodyingmyinvention; Figure 2 is a top plan view thereof with the handleomitted;

Figure 3 is an end view thereof.

the passage of the lever and hooks. The

pivots for the levers are so located with 'respect to their hooks thatthe tendency of embrace the post and the coil spring.

Fig. 4 is an enlarged vertical section through the center of theadjusting screw, 20 the sectionrbeing at right angles to the section ofFig. 1.

1 is the wringer frame comprising the complementary housingsections 2and 3'. 4;` and 5 are respectively the upper and lower` c0- operatingrolls .journalled 1n the bear-lugs within the uprights of the frame, theupper roll being vertically movable .toward and away from the lowerroll. 6 1s a resillent bowed member extending above the u per roll 4 andconnectedto its bearmgs y a slotted strap 6 through which the springextends to raise and lower the same. .7 1s a ost extending through thetop rail of the ame and transversely of the bowed member, this postbeing operatively connected to the bowed member by means of the clip 8.9 is a handle upon the post andabove the wringer frame for facllitatlng.1n the manual inward longitudinal adjustment of the post to press theupper roll into contact with the lower roll.

- For holding the post in an inwardly adjusted position, I have providedthe catch 10 in the form of hooks 11 which extend upwardly above the toprail of the frame and engage over the shoulder formed by the nut 12 uponthe *Elst 7 and also located above the top rail. e trip for releasingthe ca tch comprises the releasing levers 13 extending above the toprail and 'pivoted thereto at 14, the hooks extending upwardly from theselevers and preferably being integral therewith. The top rail is cut awayat 15 for the post to move longitudinally outward does not eil'ect therotation ofthe levers to disengage the hooks from the nut, andfurthermore, the levers have at their inner ends the intermeshng fingers16. v l

For the purpose of moving the upper roll away from the lower roll uponreleasing the v d post, I have provided the coil spring 17 mclosedwithin the top rail of the frame' and surrounding the post, the upperend of this coil spring being secured to the sleeve 18 which'is suported upon the cooperating inner ends o the levers 13 which The lowerend of this coil spring is secured to the clip 8. For the purpose ofvarying the longitudinal inward movement of the its outer end isthreaded and the nut 12 is rotatable aboutthis outer end to vary itslongitudinal position relative tothe post.

19 is a drain board extending below the rolls 4 and 5, this drain boardbeing laterally adjustable to'either side of the rolls. rigidly lockingthe drain board in its positio'n of adjustment I have provided thestrips 20 forming projections upon the inner sides of the dependingflanges 21 of the frame, which strips engage in the elongated openings22 located in the depending side flanges 23 of the drain board. Theseopenings have the diverging downwardly-and outwardly inclined upperedges 24 at the intersection of which depending lugs 25 are located, thearrangement being such that the strips when clampedagainst either upperedge has its ends adjacent to an end of the opening and the lug 25 sothat lateral movement of the drain board is impossible.

For clamping the drain board in its adjusted positions, there is the rod26 having the transversely bent end 27, this rod being journalled in thedepending flanges 21 extending through the elongated openings 22. Therod has the cam port1ons`28 engageable with the lower edges of theelongated openings to,v force the drain board downwardly relative to thewringer frame and clam the For post,

strips 20y against the upper edges o the openings.v The cam portions ofthe rod are -formed merely by transversely cutting.

away portions thereof a suicient distance to permit of lateraladjustment of the drain frame, of upper and lower rolls withinsaidframe, 4a ost extending transversely of said upper ro l, said postbeing longitudinally movable inward to press said rolls into contactwith each other, a coil spring surrounding said post, means conveyingmovement from said post to the upper roll and -operatively connected tosaid spring and upper roll for resiliently moving the up er roll awayfrom said lower roll, a nut t readed upon said post, a releasing leverpivoted upon said frame and extending thereabove, and a catch actuatedby said lever and en gageable with said nut to hold said post in aninwardly adjusted position.

2. In a wringer, the combination with a frame, of upper and lower rollswithin said frame, a member extending above said upper roll andoperatively connected to the same, a post extending through said frameand transversely of and operatively connected to'said member, a nutthreaded upon said post above said frame, a trip pivotally mounteduponsaid frame, a catch actuated lnesaaaa upper roll.

3. yIn a wringer, the combination with a frame, of upper and lowei`rolls within said frame, a resilient member extending above said upperroll and operatively connected to the same, a post extending throughsaid frame', and transversely of said `resilient member, means forsecuring said ost to said resilient member, a nut threade upon said postabove said frame, releasing levers pivotally mounted upon said frame andhaving intermeshing inner ends, and extensions projectin over said nutand adapted to engage sai nut when said post isin an inwardly adjustedposition, a sleeve surroundingi said post and supported. upon the inneren s of said releasing levers, and a coil spring surround' said post andsecured -to said sleeve an clip.

In testimony whereof' I aix my signature.
